Create Unicode Strings from Array Elements

6 posts in this topic

Given the following array

$aFL = ['File50','File10','File12','File38','File00100','File001']

My understanding up till now is that each element is an ASCII string.  How do I make them unicode?

You can put unicode strings into arrays just be using Unicode characters.

Global $aArray[1] = ["באָבקעס מיט קודוצ׳ה"]
MsgBox(0, "", "$aArray = " & $aArray[0] & @CRLF)

You have to make sure the encoding in SciTE is set to one of the UTF options, File => Encoding => UTF8 with BOM works for the above code. You should see the same text in the message box as you do in SciTE.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

#include <Array.au3>
Local $aFL[6] = ['File50','File10','File12','File38','File00100','File001']
For $i = 0 To UBound($aFL)-1
    Local $aTemp = StringToASCIIArray($aFL[$i])
    $aFL[$i] = _ArrayToString($aTemp,"")
Next
_ArrayDisplay($aFL)

Return valud from StringToASCIIArray:

Success: An array where each element is the UNICODE code of the character at the corresponding position. Failure: Returns an empty string.

Taking your other post into consideration:

#include <Array.au3>
Local $aFL[6] = ['File50','File10','File12','File38','File00100','File001']
For $i = 0 To UBound($aFL)-1
    Local $aTemp = StringToASCIIArray($aFL[$i])
    For $j = 0 To UBound($aTemp)-1
        $aTemp[$j]=StringFormat("%03s",$aTemp[$j])
    Next
    $aFL[$i] = _ArrayToString($aTemp,"")
Next
_ArrayDisplay($aFL)
_ArraySort($aFL)
For $i = 0 To UBound($aFL)-1
    $aTemp = StringRegExp($aFL[$i],"\d{3}",3)
    $aFL[$i] = StringFromASCIIArray($aTemp)
Next
_ArrayDisplay($aFL)

You don't have to do anything: all native AutoIt strings are stored and processed as UCS-2 (roughly = Unicode plane 0) i.e. every character in a string is represented by a single 16-bit Unicode codepoint.

As BrewManNH said, you obviously need to set source file encoding to UTF8+BOM to represent characters outside your active codepage. When not using UTF encoding, extended ASCII characters (in [0x80..0xFF]) in the source file are subject to interpretation under the currently active codepage. That means that if you expect source portability accross users using different codepages, you need to use UTF encoding. But whatever encoding is used in the source, the compiled executable will be portable*, since string literals are stored in UCS encoding inside the .EXE.

* but only if you don't use Chr(value) with value > 0x7F. OTOH ChrW(value) will be portable. Also basic ConsoleWrite output is codepage dependent. Using CP 65001 as default codepage (switch console to Unicode) restores the portability.

Thanks, jchd, my question was related to this >thread.
